Abstract

An aqueous suspension of coagulatable material is coagulated by adding polymeric coagulant to the suspension and then separating the resultant coagulated material from the liquor. The coagulatable material may be present in the aqueous suspension as a suspension of suspended solids or as colloidally dispersed solids. The suspension may be coal tailings or other aqueous (gen-erally mineral) suspension. The polymeric material must be a low molecular weight, highly ionic, polymeric material. It is added to the aqueous suspension while in the form of polymeric particles having a size mainly above 30 µm and that will dissolve into the suspension and coagulate the coagulatable material. A counterionic, high molecular weight, flocculant is generally added sub-sequently in order to flocculate the coagulated material.
